    Bio-medical waste is generated mainly by health care establishments. The management of Bio-medical waste is still infant all across the world. It consists of Bio-medical waste as well as chemical waste with a portion of solid waste. This is a review paper which is prepared from the surveys of various research papers on improper biomedical waste. This research article is to survey the practice of biomedical waste such as collection, storage, transportation and disposal along with the amount of generated biomedical waste in various hospitals. Biomedical waste management is one of the biggest challenges of the present day times. It has a direct impact on the health of the citizen of that city. It is hazardous in nature. It’s safe and proper disposal is extremely important. As in many developing countries the generation of biomedical waste has increased significantly over the last few decades, management of this kind of waste continues to be a major challenge. Biomedical waste is generated in hospitals, research institutions, health care teaching institutes, clinics, laboratories, blood banks, animal houses and veterinary institutes. For proper management of bio-medical waste the Ministry of Environment and Forests has promulgated the Bio-Medical Waste (Management and Handling) Rules, 1998. Purpose of study was to highlight certain aspects of hospital waste management status. This paper will sensitize the reader about the impacts of improper waste management. Proper handling, treatment and disposal of the biomedical waste material are most important issue for the health of the human beings. The inadequate knowledge about the proper handling of biomedical waste can be dangerous to the health of common man as well as of health care personnel. This review discusses about various types of waste, its hazards and management

    Query Processing on Encrypted Database: A Performance Evaluation

    Due to the rapid development of the global internetworked infrastructure, the research scope of secure data management has been greatly expanded. Now due to the openness of the internet, databases are accessed by legitimate authorized users as well as the outsiders. So the problems in traditional database security need to be revisited and readdressed in decentralized web-based and open environments. Secure and efficient algorithms are needed that provide the ability to query over encrypted database and allow optimized processing of data. Clearly, there is a compromise between the degree of security provided by encryption and the efficient querying of the database, because the operations of encryption and decryption greatly degrade query performance. We evaluate the performance of the query processing over encrypted database with algorithms REA and with most common algorithms: AES and RC6. The performance of the query over encrypted databases using AES, RC6 and REA algorithms are compared. This performance measure was conducted in terms of query execution time. The experiment results show the advantages of the algorithm REA over other algorithm AES and RC6 in terms of the query execution time. The results show that the encryption algorithm REA outperforms other encryption algorithms at performance and security in databases. The performance of the query enhanced if we encrypt the database by using REA algorithm. So it has achieved security requirements and is fast enough for most applications. REA algorithm is limiting the added time cost for encryption and decryption to do not degrade the performance of a database system. DOI: 10.17762/ijritcc2321-8169.160413

    Gauss Legendre Quadrature Formulae for Tetrahedra

    In this paper we consider the Gauss Legendre quadrature method for numerical integration over the standard tetrahedron: {(x, y, z)| 0 ≤ x, y, z ≤ 1, x + y + z ≤ 1} in the Cartesian three-dimensional (x, y, z) space. The mathematical transformation from the (x, y, z) space to (ξ, η, ζ) space is described to map the standard tetrahedron in (x, y, z) space to a standard 2-cube: {(ξ, η, ζ)| − 1 ≤ ξ, η, ζ ≤ 1} in the (ξ, η, ζ) space. This overcomes the difficulties associated with the derivation of new weight co-efficients and sampling points. The effectiveness of the formulae is demonstrated by applying them to the integration of three nonpolynomial and three polynomial functions

These changes may be :Routine - as the ship is loaded/unloaded in harbour or due to consumables enroute.Emergency - when the ship suffers collision/battle damage underway and begins to take on water.After assessing the stability status, the program helps the crew to determine the actions needed to restore optimum stability

    Ayurvedic interventional management of Manyagatavata w.s.r. to Cervical Spondylotic Myelopathy (CSM) - A Case Study

    Get PDF
    Cervical Spondylotic Myelopathy (CSM) is a degenerative spinal disease which may lead to significant clinical morbidity. The onset of symptoms is usually insidious, with long periods of fixed disability and episodic worsening events. Regarding the pathophysiology of CSM, the repeated injuries to the spinal cord are caused by both static and dynamic mechanical factors. Only limited surgical procedures, neuroplasticity and other medical interventions are employed in modern medicine.  The standard treatment for moderate to severe CSM is operative procedures which are least preferred by the elderly patients. Hence there is a need to search for effective treatment in alternative medicine. According to Ayurveda, cervical spondylosis can be co-related with Manyagatavata, a type of Vataja Vyadhi. A 48 years old male patient presented with Neck pain, neck stiffness, and back pain since 4 years. Here, we are presenting a case of Cervical Spondylotic Myelopathy (CSM) which was treated with Ayurvedic Panchakarma procedures such as Virechana with Mahatikta Ghruta, Tiktaksheera Basti, Greeva Basti, Nasya Karma with Vacha Taila along with Ayurvedic oral drugs like Tab Brihatvata Chintamani Rasa, Ashvagandha Churna with Kavacha Beeja Churna, Amruta Guggula, Ekangaveera Rasa and Chaturbhurja Rasa. These entire drugs were prescribed for twice a day after meals. This case report revealed usefulness of Panchakarma procedures and Ayurveda oral medicines in the management of Manyagatavata w.s.r. to Cervical Spondylotic Myelopathy (CSM)

    Background: Ropivacaine is more selective for sensory fibers when compared to other local anesthetics, producing less motor block. This permits better maternal ambulation and also allows for normal progression of labor, which translates into lesser instrumental deliveries and higher vaginal deliveries. Objective was to evaluate 0.125% versus 0.2% ropivacaine, with 2 μg/ml of fentanyl in epidural labor analgesia, regarding their sensory and motor block characteristics.Methods: This prospective study was conducted among 40 patients, 20 in each group [group A (0.125% ropivacaine with 2 µg/ml fentanyl), group B (0.2% ropivacaine with 2 µg/ml fentanyl)], for epidural labor analgesia in obstetrics and gynecology department (labor room). The efficacy of the drugs was tested by comparing the onset of analgesia, duration of labor analgesia, dose requirement, pulse, BP, sensory effect, motor effect, FHR, APGAR score and side effects.Results: Total duration of labor analgesia was 230.25 minutes with 55.68 SD and 186.25 minutes with 57.7 SD in group A and group B respectively (p<0.05). The total dose of ropivacaine used was 81.00 mg and 68.50 mg in group A and B respectively (p<0.05). Total dose of fentanyl required was 94.50 µg and 73.50 µg in group A and group B respectively (p<0.05). There was no significant difference found in hemodynamic parameters in both groups.Conclusions: Both the concentrations are effective in producing epidural labor analgesia. However, onset of analgesia was significantly faster with 0.2% ropivacaine. The required dose of ropivacaine was significantly higher in 0.125% ropivacaine. 0.2% ropivacaine shorten the duration of labor compared to 0.125% ropivacaine
